Confirmation completes Christian initiation through the laying on of hands and anointing with chrism oil. It strengthens baptismal grace and obliges Catholics to publicly profess their faith. Though originally part of baptism, it separated over time and is now conferred by bishops upon adolescents to make them soldiers of Christ. Candidates prepare through acts of service, retreat, and regular Mass attendance before receiving the Holy Spirit's gifts of wisdom, understanding, counsel, fortitude, knowledge, piety and fear of the Lord.
